1-3 Installation of the CPU and Heatsink
English
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the pin one marks on the processor and socket. If you install the
CPU in the wrong direction, the CPU will not insert properly. If this occurs, please
change the insert direction of the CPU.
3. Please add an even layer of heat sink paste between the CPU and heatsink.
4. Please make sure the heatsink is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It is not
recommended that the system bus frequency be set beyond hardware specifications since it
does not meet the required standards for the peripherals. If you wish to set the frequency
beyond the proper specifications, please do so according to your hardware specifications
including the CPU, graphics card, memory, hard drive, etc.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system requires all
of the following platform components:
- CPU: An Intel® Pentium 4 Processor with HT Technology
- Chipset: An Intel® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled
- OS: An operation system that has optimizations for HT Technology
1-3-1 Installation of the CPU
Raise the processor
socket handle to 65
degrees.
Fully raise the processor socket handle.
1. Raise the processor socket handle to
65 degrees. You maybe feel a kind of
tight.

4. Locate Pin One in the socket and
look for a (golden) cut edge on the
CPU upper corner. Then insert the
CPU into the socket and close the
socket handle.
1-3-2 Installation of the Heatsink
1. Push down the cooler clip to secure to the
retention mechanism hooks for all four corners.

00
0 We recommend you to apply the thermal tape to provide better heat conduc
00
tion between your CPU and heatsink. (The CPU cooling fan might stick to the
CPU due to the hardening of the thermal paste. During this condition if you
try to remove the cooling fan, you might pull the processor out of the
CPU socket alone with the cooling fan, and might damage the processor. To
avoid this from happening, we suggest you to either use thermal tape in
stead of thermal paste, or remove the cooling fan with extreme caution.)
00
0 Make sure the CPU fan power cable is plugged in to the CPU fan connector,
00
this completes the installation.

procedure.
2. Plug the cooler power cable into the CPU fan
connector on the motherboard.

1-4 Installation of Memory
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is recommended that
memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be
installed in only one direction. If you are unable to insert the module, please switch the
direction.
The motherboard has 2 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary between
sockets.

With the use of the power connector, the power supply can supply enough stable power to all
the components on the motherboard. Before connecting the power connector, please make sure
that all components and devices are properly installed. Align the power connector with its
proper location on the motherboard and connect tightly.
Please use a power supply that is able to handle the system voltage requirements. It is
recommended that a power supply that can withstand high power consumption be used (300W
or greater). If a power supply that does not provide the required power is used, the result can
lead to an unstable system or a system that is unable to start.
